What Process Automation does

Process Automation (Pty) Ltd is a South African industrial measurement systems manufacturer founded in 1980, headquartered in Randburg, Johannesburg, with a 12,500m² SANAS-accredited, ISO 9001-certified production facility and five domestic branches across South Africa's major mining regions. The company designs and builds custom-engineered conveyor belt scales, gamma-ray density gauges, weigh feeders (belt, screw, and change-in-weight), level measurement, blocked chute detection, metal detection (Tectron brand), moisture measurement, radiation measurement, speed sensors, and blending/batching systems, all unified through its proprietary UNIPRO/UNIPROM modular transmitter platform that supports industry-standard fieldbuses including ProfiBus DP/PA, Ethernet/IP, DeviceNet, ControlNet, MODBUS+, and MODBUS RTU. Process Automation's commercial model is built on direct enterprise field sales to large mining houses and process industry operators, with all equipment quote-based and configured to site-specific application requirements, supplemented by 24-hour field service, equipment repairs, refurbishment, preventative maintenance, and operator training delivered through its branch network. International reach is achieved through named agents and distributors in Chile, Peru, Canada, Zimbabwe, and Namibia, plus complementary reseller lines (MoistTech, Hawk Instruments, SCAIME) that broaden the portfolio without internal R&D spend. A November 2025 partnership with Razor Labs layers AI-powered predictive maintenance (DataMind AI platform) onto the installed base, representing an early move from pure hardware sales into recurring, software-enabled service revenue.
